The JBX42624 65-meter FC/APC to ST/UPC duplex singlemode fiber patch cable represents professional-grade connectivity engineered for demanding network environments. This cable combines precision connector technology with high-quality glass fiber to ensure reliable, long-distance signal transmission. Key Technical Specifications: This duplex cable features 9/125 singlemode fiber cores with G.657.A1 glass composition, delivering superior performance for both 1310nm and 1550nm wavelengths. The cable achieves exceptionally low attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm, with insertion loss maintained at ≤0.35dB and return loss ≥20dB. These specifications exceed ANSI/TIA/EIA standards, ensuring optimal signal quality across the entire 65-meter span. Connector Configuration: The FC/APC to ST/UPC crossover configuration (Type A to B) represents the industry standard for duplex patch cords, providing seamless compatibility with existing network infrastructure. FC/APC connectors feature angled polished surfaces minimizing back-reflection, while ST/UPC connectors offer straightforward mechanical reliability. Compliance & Safety: TAA compliant and RoHS certified (EU directive 2002/95/EC), this cable meets government procurement standards and environmental requirements. The riser-rated OFNR jacketing provides fire-safe performance for indoor installations, with a 1.8mm outside diameter ensuring manageable routing through conduit and cable trays. Applications & Use Cases: Ideal for data center interconnections, telecommunications infrastructure, long-distance signal transmission, and enterprise network backbone installations. The 65-meter length eliminates the need for intermediate splitters in many applications, reducing signal loss and complexity. Custom Solutions: Custom lengths available upon request, allowing optimization for specific installation requirements. Multiple U.S. distribution points (California, Texas, South Carolina) enable rapid delivery. Warranty & Support: Backed by a 90-day limited warranty, this cable represents a reliable investment in network infrastructure quality and longevity.
